Craig "133" Jones (born Craig Michael Jones on February 11, 1972) is a music sampler and keyboardist best known as member #5 of the band Slipknot. He is also in charge of the digital media in the band.

In the early days, Jones originally joined Slipknot as a guitar player to fill in for Donnie Steele, but later switched to being in control of the samples, working with DJ Sid Wilson. Craig Jones also controls the guitar effects used live. His mask in the early days of Slipknot was a diving helmet with long needles, but eventually switched to a tight spandex mask with nails each nine inches long, one inch for each band member. There is a theory, however, that Craig was inspired by the band Nine Inch Nails, and the length of the nails are his tribute to that band. Regardless of the nails on his mask, Jones has only had one incident with them. Once when the band was leaving from a concert, fans rushed up for autographs behind the band. Jones was not expecting this and quickly whipped around, only to accidentally get a female fan's hair tangled within his nails. Fortunately, the outcome was minor and far from severe. It took Paul and Shawn only a few seconds to untangle the hair. This seems a bit ironic, considering his quote, "Sometimes, when we are working our way up to the stage, we'll shove our way through the crowd. When people see me coming, they mostly get out of the way. But sometimes they don't..."

While all of the Slipknot band members wear their stage masks in the public eye, most have been seen without their masks, mainly due to side projects the members have been involved in. Jones is the most elusive face of Slipknot, and until the "Duality" video shoot in Des Moines, Iowa, no fan had ever seen his true face knowingly.

He is a video game fanatic and gets his ideas for samples in songs from movies. For example, the line "Here comes the pain" in the track "(Sic)" was taken from Carlito's Way; the voice was of Al Pacino. The opening track for their self-titled album was created by Jones, and the dialogue in the background, "The whole thing I think, is sick", was taken from a Charles Manson documentary. He is known for his variety in instrumentation in his samples, effects and keyboards. Some few notable examples of his variety include techno (The Nameless, My Plague), Voice/speech sampling (742617000027, (Sic), The Blister Exists, The Heretic Anthem), Piano (Duality, Vermilion Pt. 2), Percussion effects (Wait And Bleed, Surfacing), Sampled back-up vocals by Corey Taylor when songs are played live (Wait and Bleed, The Nameless) Distorted gothic sounds (Vermilion, Left Behind), Tape Recorders ((Sic), Circle), Fast distorted effects (Spit It Out, 742617000027), Guitar effects (Before I Forget), Progressive Electronica (Circle, Prelude 3.0) distorted electronica (The Blister Exists, Tattered and Torn) and various effects such as Air Raid Sirens (Pulse Of The Maggots, No Life) and atmospheric backdrops (People = Shit).

Jones is in charge of the official Slipknot website[1], which he once ran with his wife before their divorce. His ex-wife died on May 3, 2005.
